Abstract

Magnetic coupling device, particularly for centrifugal motor-pumps, between two rotors separated from each other by a watertight wall of magnetic material, and presenting, for a given relative angular position, facing each other, an even number of permanent magnet poles of opposite polarities, characterized in that the permanent magnets of the motor-side rotor are different in nature from those of the pump-side rotor, the ones, preferably those of the motor-side rotor, being of a material that has a very strong remaining induction, of the order of 10,000 Gauss or more, such as a magnetic steel alloy containing iron, cobalt, nickel, aluminum, copper and eventually titanium (Ticonal or similar), while the others are of a material that has a coercive field raised to 1,500 erstediums or more, such as a hard ferrite, specifically a barium oxide ferrite (eg Ferroxdur I).
